The purpose of the study was to analyze Japanese recognition and image about Oriental representative martial arts (Taekwondo, Wu Shu, t``ai chi, Judo and Karate) and to apply the analysis to an increase in variety and influence of Korean martial arts including Taekwondo with people of Japan where had variety and influence on Oriental martial arts and came to modernization in advance. The study got the below conclusions by analyzing Japanese recognition and image about five Oriental martial arts. First, Taekwondo was not included in items which Japanese people associated the most early with the word of martial arts. Second, they didn`t have other images of Taekwondo excepting kicking, South Korea and Olympic in their association by each item. Namely, it is necessary to make a concrete plan to stimulate people`s association for development of Taekwondo. Third, they had similar images of four martial arts excepting Taekwondo. Changes of image are not connected with good results at all times. However, it is necessary to make an additional endeavor to secure more popular image by keeping core images such as quick kicking.

Korean churches have introduced and utilized physical activity programs in taking pastoral duties so that various programs, in which christians and non-christians participate, have been carried out. The physical activity programs help to increase the organizational force of church followers and improve the church image through the natural promotion to non-christians, and have been used as a tool of missionary work. But, the way to follow the programs unconditionally without professional knowledge or concrete methodology is considered negative in a society, and leads to the decrease in church followers’ satisfaction with church. Therefore, this study was intended to define the structural relations with church satisfaction and loyalty, organizational devotion, and word-of-mouth intention according to the physical activity participation of christians, and consequently propose a method to help each Korean church properly apply the physical activity programs utilizing sports to pastoral duties and utilize them as an effective tool of missionary work. Accordingly, to investigate the relation of cause and effect on church satisfaction, loyalty, organizational devotion, and word-of-mouth intention through christians’ participation into physical activities, this researcher selected as the population group mid-and large-sized churches with more than 1000 to less than 2000 registered followers and physical activity program facilities located in the Metropolitan area in 2011, and extracted samples by using systematic cluster sampling. Through the preliminary survey, factor analysis was performed, and survey questions were modified and supplemented. A total of 600 people participated in the questionnaire survey, but 8 people who didn’t respond to the survey was excluded so that 592 copies were distributed. Also, 16 copies, which had some questions omitted or insincerely responded so that it was hard to conduct statistical analysis, were excluded. As a result, valid 576 copies of the questionnaire were finally used for empirical analysis. As for the analytical materials, SPSS Windows V17.0 program and AMOS 16.0 program was used for analysis. This study used the following statistic schemes for data processing. First, to verify the validity and reliability of questionnaire copies collected in this study through the preliminary survey. Exploratory Factor Analysis (EFA) and reliability test were performed. Secondly, to analyze the relation of cause and effect on church satisfaction, organizational devotion, loyalty, and word-of-mouth intention through christians’ participation into physical activities, AMOS 16.0 was used to apply the measurement errors of main theoretical variables to a model so that Structural Equation Model (SEM) analysis, which helps to investigate the direct and indirect effects of variables, was performed. And, to prove that each one of theoretical hypotheses set in this study was discriminated empirically, Confirmatory Factor Analysis (CAF) was conducted. Sixthly, to analyze christians’ perception of participation into physical activities, Frequency Analysis through Multiple Response Group analysis was conducted. After analyzing the materials on the basis of the study methods described earlier, this researcher drew the following conclusion. The result of the analysis on the relation of cause and effect on church satisfaction, organizational devotion, loyalty, word-of-mouth intention through christians’ participation into physical activities presented that, regarding the relation between the satisfaction with external factors of church and word-of-mouth intention, the factors of organizational devotion and loyalty were found to have statistically significant indirect effects, and, regarding the relation between the satisfaction with internal factors of church and word-of-mouth intention, the factors of organization devotion and loyalty were found to have no statistically significant indirect effects.

본 연구에서는 산사 발효초가 고지방식이를 급여한 흰쥐의 지질대사에 미치는 영향에 대해 살펴보았다. 흰쥐에게 고지방식이(40% kcal% fat, beef tallow)를 급여하면서 산사 발효초를 저농도(1.5% wt/wt, n=8), 고농도(3.0% wt/wt, n=8)로 투여하였을 때, 정상식이군(n=8)과 고지방식이 대조군(n=8)과의 체중, 장기무게, 지질 함량 등의 차이를 관찰하였다. 체중은 산사발효초군이 정상식이군보다 유의적으로 증가하였지만, 고지방식이 대조군보다 유의적으로 각각 7.2%, 10.0% 감소하였다. 간과 신장 무게도 고지방식이 대조군에 비해 산사발효초군들에서 유의적으로 감소하였다. 고농도 산사발효초군에서 혈청의 중성지방, 총콜레스테롤, LDL-C, 동맥경화지수 및 간의 중성지방, 총콜레스테롤 함량은 고지방식이 대조군에 비해 유의적으로 감소하였지만 혈청 중 HDL-C 함량은 유의적으로 증가하였다. 분변 중포화지방산 함량은 고농도 산사발효초군에 비해 정상식이 군이나 고지방식이대조군에서 유의적으로 높았다. 결론적으로 산사발효초는 체중을 감소시키며 혈청이나 간의 지질함량을 개선시키고, 포화지방산 배설을 증가시키므로 체중조절 및 지질대사 개선 효과가 규명되었다. Crataegi fructus has been used as an oriental medicine and a folk remedy for the treatment of scurvy, constipation and stomach ailment. This study was aimed to investigate the effect of fermented Crataegi fructus vinegar (FCV) on the improvement of lipid metabolism in rats fed high fat diet (40% kcal% fat, fat source; beef tallow). Sprague-Dawley rats (n=32) were randomly divided into four groups [normal diet (ND), high fat diet (HD), and high fat diet supplemented with low (CFL; 1.5% wt/wt) and high (CFH; 3.0% wt/wt) doses of fermented Crataegi fructus vinegar] and were fed experimental diets for 6 weeks. At the end of the experiment, the body weight in high fat diet groups was higher than that of normal diet group, while the body weights of CFL and CFH group were significantly reduced by 7.2% and 10.0%, respectively, as compared with that of HD group. Moreover, liver and kidney weights in CFL and CFH group were significantly lower than that of HD group (p<0.05). The levels of serum triglyceride, total cholesterol, LDL-C, atherogenic index and hepatic triglyceride, total cholesterol in CFH group were significantly decreased as compared with HD group whereas it increased the serum level of HDL-C than HD group (p<0.05). CFL and CFH groups showed significantly decreased AST, ALT and ALP of serum as compared with HD group. Excretions of fecal saturated fatty acid in CFH group was significantly increased compared with ND and HD groups. These results imply that fermented Crataegi fructus vinegar can be used as possible food resources and functional food materials.

In this paper, a conceptual design and a detailed design of novel cylindrical magnetic levitation stage is introduced. This is came from planar-typed magnetic levitation stage. The proposed stage is composed of cylinder-typed permanent magnet array and semi-cylinder-typed 3 phase winding module. When a proper current is induced at winding module, a magnetic levitation force between the permanent magnet array and winding module is generated. The proposed stage can precisely move the cylinder to rotations and translations as well as levitations with the magnetic levitation force. This advantage is useful to make a nano patterning on the surface of cylindrical specimen by using electron beam lithography under vacuum. Two methods are used to calculate required magnetic levitation forces. The one is 2D FEM analysis, the other is mathematical modeling. This paper shown that results of two methods are similar. An assistant plate is introduced to reduce required currents of winding module for levitations in vacuum. The mathematical model of cylindrical magnetic levitation stage is used for dynamic simulation of magnetic levitations. A lead-lag compensator is used for control of the model. Simulation results shown that the detail designed model of the cylindrical magnetic levitation stage with the assistant plate can be controlled very well.
